Biotech: The future of farming

Available for over a year

Does farming as we know it have a future? We hear from those who argue biotechnology is about to disrupt agriculture for good. Shifting diets and food sources will put one million US farming jobs at risk, according to futurist Tony Seba of the think-tank Rethink X. But cattle farmers are not about to give up their livelihoods so easily. We hear from British farmer Andrew Loftus and Danielle Beck of the National Cattlemen’s Beef Association in the US. Manuela Saragosa also speaks to Henning Steinfeld at the United Nations Food and Agriculture Organisation. Producers: Laurence Knight and Szu Ping Chan. (Photo: a cow in a field. Credit: Getty Images)
